No one thought that it would take at least several years for Project 10 to enter the prototype trial production process.

It's only been three years since it was launched in '84!

And now, the super-7B has just started the prototype trial production work, and it has not even started its first flight, and the No. 10 project has to start the prototype trial production again.

"Is there no problem in terms of technology?" Li Mingshan asked, "If there is no problem with the technology, it is time to enter the trial production link, and it must be entered into the trial production link." ”

His concern was that 132 and 611 would be stimulated by 404's pattern.

When the technical design is not completed, the prototype trial production is started first, and the production is carried out while designing, and the production is improved while being produced.

Project 10 was a key national defense project, and it was the Air Force that paid for it.

404 is different, it is originally a Sino-foreign joint research and development project, and the research and development funds are partially borne by foreign countries, and even there will be orders after design and production. 404 has more funds in his hands than the entire country's military budget in a year, and it is not a problem at all to use money to smash it.

"Chief, after the J-9 lowered the original performance indicators in 75 years, it was basically close to success when it was launched...... The main reason for the initial dismount was that the technical difficulty was too great, and the supporting system could not keep up. And with the change of use, some of the designs in the original development process can meet the use ......"

Song Wencong, as the chief designer of Jian-10, naturally has a very high say in the entire project.

The original design index of Jian-9 is even better than Project 10 in many aspects, but it is worse than Project 10 in terms of use.

After all, in that era, high-altitude and high-speed was the mainstream development direction of the world.

Now fighters all over the world are no longer pursuing high altitude and high speed, but instead pursuing the comprehensive performance of multi-mission mode.

In addition, some of the aerodynamic layouts proposed by Xie Kai were originally the original design of the J-10, in the design and development process of the super-7A and super-7B, at the beginning, it was originally based on 611, and later 404 continued to poach people from 601 and other domestic fighter design units, and they were all technical backbones, so they slowly became cooperation.

A lot of the designs are from 404, and all the design team needs to do is keep arguing whether these designs are useful or not.

"The avionics system is also solved?"

"404 has a pulsed Doppler radar, which belongs to a multi-control array focal plane radar. The maximum search range is 120 km, the upward range is 70 km, the downward range is 60 km, and the rear range is 30 km. Simultaneously track 16 targets and attack 8 of the most threatening air targets...... This radar is what they are going to use on the Super-7B. Xiong Hongyuan hurriedly said.

It's not that he doesn't want to say.

If Project 10 starts trial production of prototypes, the fire control radar will really have to be provided by 404.

After all, the J-10 is similar to the Super -7B in many aspects, and the performance is comparable, which is suspected of grabbing funds.

Whether it is Super -7A, Super -7B, or Project 10, these three types of fighters are very similar in many aspects.

Originally, they all came from the dismounted J-9.

"In this way, if the Super 7B uses a twin-engine turbofan-6G, can the maximum take-off weight exceed 25 tons?" Li Mingshan did not receive a reply from the 404 side before.

Now that I've listened to the introduction of 611, I feel that these guys from 404 have other ideas.

It is said that the Super -7B is for the domestic Air Force, but with the investment of the Pakistanis, no matter how you think about it, you don't feel reassuring about it.

Unless the 404 is prepared at the beginning, the super-7B is still exported!

With a dead weight of 10 tons and a maximum take-off weight of 22 tons, it can carry 6 tons of ammunition even if it carries half of the fuel.

This performance is more than the ammunition that the H-6 can normally carry for bombing.

"Theoretically, yes. Turbofan-6G is currently the most important project of Dongfeng Power Plant, although the performance is good, but there is a fatal flaw...... "Xiong Hongyuan is worried that 404 will settle accounts with them when the time comes."

After all, they don't know what the 404 gang of people are thinking.

The maximum take-off weight of the Super-7A can obviously be increased even more, which is limited by them.

"What's the problem?" Long Yaohua asked puzzled.

He couldn't understand it.

He also said that it had been successfully developed, and that there were fatal flaws.

If there is a fatal flaw, can it be used?

"The service life is too short......"

"How short?"

"Without afterburner, the service life is more than 300 hours, once the afterburner is opened, especially if the afterburner is often opened, the service life is less than 100 hours......" Even if the truth is told, it may affect the prototype trial production work of the No. 10 project, and the people of the 132 factory still have no hesitation in this.

Because of its excellent performance, turbofan-6G has higher requirements for materials and manufacturing processes.

The more efficient the turbofan engine is, the higher the temperature of the combustion chamber.

The issue of basic materials has always been the key to the development of equipment and technology in various fields in China.

Long Yaohua was silent.

Li Mingshan no longer pondered the thoughts of the 404 gang that wanted to exchange the twin-engine super-7B export for development funds.

With such a service life, it is simply impossible to put it into practical use.

The service life of an engine is less than 100 hours, and the production cost is several million, and then, tens of thousands of dollars an hour of engine use cost, plus other costs, several are used for testing, and the Air Force can still support it.

Even if one regiment is equipped, the entire air force will go bankrupt.

It is no wonder that the people of 404 did not say that they would let the Air Force place an order now, nor did they introduce too much about equipping the turbofan-6G with the super-7B, but hoped that the national aviation power system would mobilize elite soldiers and cadres to work together to tackle key problems.

"If Project 10 uses a turbofan-6G engine, the cost will be ......," Li Mingshan felt painful.

The military can't afford this kind of attrition.

"Chief, in the process of trial production, we only need to allocate part of the funds, and we raise part of it ourselves. Xiong Hongyuan was afraid that the above would not agree.

Now there are a lot of production tasks in the 132 factory, and other civilian units can also bring a lot of profits, and there is no problem in supporting the prototype test and flight test of the No. 10 project.

It's a big deal, when the time comes, cheekily rob 404 of some funds.

The production unit of turbofan-6G is Dongfeng Power Plant, which is a subordinate unit of 404.

The engine of the Dongfeng Power Plant for Project No. 10 cannot be put into use at all, and they don't share some expenses, can they do it?

Long Yaohua and Li Mingshan were originally going to go back, but after learning about these circumstances, they naturally couldn't leave.

It just so happened that Zheng Yucheng and the others were all here, and took the initiative to find them and asked to go to Dongfeng Power Factory to understand the situation.

Dongfeng Power Plant has now integrated a lot of excellent aero engine design and manufacturing technicians, and at the same time, is also updating production equipment.

I heard that Long Yaohua, Li Mingshan and others came to inspect the factory, and organized a group of people to line up at the gate of the factory to welcome them.

Xie Kai is the most unwelcome to this kind of thing, but he can't happen now.

Long Yaohua and Li Mingshan crossed the welcoming team and directly asked to go to the workshop to understand the situation, which made Liao Dongfeng very upset.

From time to time, I secretly asked Zheng Yucheng and them what the big guy was doing.

"I heard that the service life of your turbofan-6 is less than 100 hours?" Long Yaohua asked before he arrived at the workshop.

Liao Dongfeng and Sun Hong's faces changed suddenly.

"Chief, if you don't use afterburner, you can still use more than three hundred hours of ......"

"When a fighter plane goes to the sky, it doesn't turn on afterburner? Or does it just fly and have fun? Or do you lose a bomb or missile in the sky and evacuate?" Li Mingshan asked rhetorically.

Liao Dongfeng suddenly said nothing.

Xie Kai saw that the two bigwigs were not good, and he didn't know where to provoke them, so he gave Zheng Yucheng a look at them, and the two old guys wouldn't go up to talk about themselves at this time, so they could only come forward by themselves, "Chief, although the turbofan-6 has completed the ground test before, the materials and manufacturing process can't keep up with ......."

"Everybody knows that. Long Yaohua was very angry at this time, "Are you going to continue to produce this kind of engine with a service life of less than 100 hours?

"Chief, our technology is ......developing," Xie Kai hurriedly explained.

The service life is less than 100 hours, which is a problem of continuous afterburner.

No one can quickly solve domestic technical problems.

"The inlet temperature of the turbofan-6G reaches 1210 ° in the normal working state, and the inlet temperature of afterburner thrust reaches 1370 °...... "Sun Hong also quickly explained.

It's not that they don't work hard, and the materials can't keep up with the manufacturing process.

"Chief, the new generation of nickel-based superalloys we have developed in cooperation with the Institute of Materials is currently in the experimental stage...... As long as it succeeds, the problems encountered by the turbofan-6G engine will be effectively solved. Zheng Yucheng understood why Long Yaohua and the others were angry.

Turbofan-7G engine for the Super -7B used by the domestic Air Force!

"Yes, chief, not only will the material problem be solved, but even the manufacturing process, we have a large press, and the impeller after die-casting can withstand higher temperatures......" Xie Kai also understood why Long Yaohua was angry.

The big guys are worried that they will use this deliberately for the Air Force, and then the Air Force will not be able to use it, so they can justifiably export this kind of fighter.

No one can do anything about the engine.

The development of the turbofan-6G, because the J-9 and Qiang-6 of the applicable objects were dismounted, stopped in 83, and finally, was canceled in 84.

Historically, the No. 10 project was launched in 84 years, but the turbofan-6 could not meet the needs of the No. 10 project, and the domestic and international engine technology level was further expanded, and it was not until October 87 that the turbofan-10 supporting the J-10 was established.

Now, Xie Kai's butterfly has fanned its wings, the No. 10 project has accelerated, and the turbofan-10 project, which was supposed to be carried out by 606, has not heard any news until now.

Dongfeng Power Plant, on the other hand, is ready to launch a thrust-to-weight engine with a thrust-to-weight ratio of more than 10!
